STANDARD.

SPECIFICATION forming part of Letters Patent No. 758,089, dated A ril26, 1904.

Application filed February 5, 1904. Serial No. 192,190- (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER M. MoYLAN, a citizen of the United States,residing at Gentury, in the county of Escambia and State of Florida,have invented certain new and useful Improvements in Standards, of whichthe fol' lowing is a specification.

This invention provides a peculiar construc-- tion of standardorstanchion to be attached to unloading of the vehicle.

the merits thereof and also to acquire a knowledge of the details ofconstruction of the means for effecting the result reference is to behad to the following description. and accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferredembodiment of theinvention is illustrated in the accompanying drawings, in which- Figurel is a front elevation showing the standard in working position, thedotted lines indicating the positions assumed by the standard and thelocking parts when the standard is released in unloading the vehicle towhich it is applied. Fig. 2 is a combined view in perspective of thelock-brace, lock-dog, and

standard, the latter being broken away. Fig.

3 is a view in elevation of a modified form of Fig. 4 IS a view inelevation means cooperating with the lock-brace. Fig.

'5 is a plan view, parts broken away, of the, -modified invention shownin Fig. 4:.

Corresponding and like parts are referred to in the followingdescription and indicated in ail the views of the drawings by the samereference characters. f a 1 held in an upright position. stantiallyreinforce the engagement of the In the drawings the invention is shownapplied tothe end portion'ofa car-bolster, though it will be understoodthat the standard is susceptible of use in connection with variousclasses of vehicles where a device of the class to which my inventionrelates could be used advantageously.

The standard comprises a body 1, which is provided at its upper end-with a chain-hook,

I sition, said brace 3 being provided at its lower end with a lockingextension 12, which engages the lower end of the arm 2 of the standardto rigidly hold the standard in the po- In order to hold the lockbrace-3' in the engaging position above described, the lock member or dog5 isutilized, which member 5 is pivoted to the pivotal member 7, upon whichthe standard is mounted. The lock-dog 5 is provided with the lug 6,which engages a projection extended laterally from the upper end of thebrace 3. Since the lock-brace 3 when attached to the support is mountedin about the same plane of movement as the arm 2 of the standard, it isnecessary to provide the projection 4. or some equivalent means withwhich the dog 5 is adapted to engage.

It will be noted that when the brace 3 is in the engaging position(indicated in Fig. 1)

and locked by dog 5 the standard 1 is firmly To more subparts abovementioned, the arm 2 of the standard is provided upon its rear side witha rib 'sition clearly shown in full lines in Fig. 1.

.or tongue 10, and the portion of the brace 3- lines in Fig. 1.

which comes into contact with the rear side of the arm 2 is likewiseprovided with a matching tongue or, groove 8, which receives the rib 10,establishing an interlocking connection throughout the length of theparts 2 and 3, which reinforces the parts in a manner which will beappreciated. With a view to further reinforce the interlockingconnection of the parts the projection 4 of the brace 3 is provided uponits upper side with spaced lugs 9, between Which the lock-dog 5 isreceived when the latter engages the brace. The pin 11 is projected fromthe support to which the standard is attached, and this pin normallysupports the lock-dog, the outer end of which rests upon the pin in aposition readily admitting of the engagement of the said dog 5 with thebrace 3. The end portion of the dog 5 which rests upon the pin 11 is theportion which is lifted or tripped in effecting the movement of thestandard 1 in unloading.

, When the dog 5 is moved upwardly, the lug 6 disengages from the upperend of'the brace 3, and'the weight of the load instantly throws thestandard in the position shown in dotted The downward movement of thedog 5 is of course limited by the pin 11. The arrangement or disposal ofthe parts of the device upon the bolster or support adunits of trippingthedog 5 without danger to the operator, and this is of no smallimportance in that a great number of accidents are caused by falling ofa part of the load upon the one who displaces the stanchion or standard.Further, the parts of the device are always in working position andready to be operatedwhenever desired.

In Fig. 3 a slightly-modified form of lockbrace 3 is shown. This partsupports the standard in the same manner as that illustrated in Fig. 1,but does not have the extension 12, which interlocks with the arm 2 ofthe standard, as described in the preferred form of the invention. Thecooperation between the dog 5. and the part in Fig. 3 and the generalmounting of the parts in this construction are substantially the same asthat in the preferred form shown in Figs. 1 and 2.

It is contemplated to make certain detail changes in the manner ofmounting the parts and the construction of the members consistent withthe spirit of the invention as found necessary in the practicalembodiment thereof.

.In certain instances it is desirable to dispose the standard centrallyupon the end portions of the bolster, as shown in Fig. 4., In order toposition the standard as above indicated without cutting a very largeportion of the bolster away, thereby impairing the strength of thebolster, the lock device is in the form of a clevis 15, which embracesthe standard upon opposite sides, being pivoted to the pivot of thestandard 1 in like. manner as the dog is pivoted in thepreferred form ofthe invention. The clevis is adapted to engage the upper end of thelock-brace, as clearly illustrated in Fig. 5. From the foregoing it willbe seen that the operating parts of the standtripping of the clevis 15to displace the stand ard from its upright position. The arm 2 of thestandard is provided with a notch 17 which is engaged by the clevis orlook device 15 on dropping of the standard, as will be clear byreference to Fig. 4. .The standard is thus utilized to hold the clevisin a position adapting same to be readily adjusted in looking engagementwith the lock-brace 3.

Having thus described the invention, what is claimed as new is 1. Thecombination with a support, a standard pivoted between its ends to thesupport, a lock brace engaging the lower end of the standard, and meansfor locking the lock-brace in the engagement aforesaid.

2. The combination With a support, astandard pivoted between its ends tothe support, a lock-brace engaging the. lower end of the standard, and alock-dog engaging the lockbrace.

3. The combination With a support, a standard pivoted between its endsto the support, a pivoted lock-brace interlocking with the lower end ofthe standard, and a pivoted lock member engaging the lock-brace.

4, The combination with a support, a standard pivoted at its lowerportion to the support, an arm projected from the standard at the pointof pivotal support thereof, a lock-brace engaging the arm of thestandard, and a lock member carried by the support and engaging thelockbrace to hold the said brace in engagement with the standard.

5. The combination with a support, a standard pivoted to the support atits lower portion and having its lower end extended to form an arm, alock-brace pivoted adjacent its lower end to the support, an engagingextension projected from the lock-brace into engagement with the arm ofthe standard, and a lock-dog mounted upon the pivotal support of thestandard and engaging the upper end of the lock-brace.

6. The combination with a support, a standard pivoted to the support, alock-brace en-- gaging said standard, a lock-dog engaging thelock-brace, and a tongue-and-groove connection between the meeting orengaging portions of thelock-brace and standard.

7. The combination with a support, a standard pivoted at its lowerportion and having its lower end extended downwardly to form an arm, alock-brace pivoted adjacent the stand- In testimony whereof I afiix mysignature in ard andengaging the arm thereof, a lock-dog preseneeof twowitnesses. mounted upon the pivotal support of the standard and engagingthe lock-brace, and a tongueand-groove connection between the meeting orengaging portions of the lock-brace and the arm of the standard.
